* Add Start/End subquery node skeleton
* Added a test query that triggers complex interna in the future and needs to proof that our work is side-effect free.
* Added first draft of ShadowRow Interface
* Refactored RegisterPlan and pulled it out of the ExecutionNode
* AqlItemBlock now has an additional hidden register to store subquery depth infromation. Right now no shadow rows are created, however thy could now make use of this situation
* Added API and test to insert new shadow rows into an OutputRow.
* Extrated test helper function
* Add template function to statically assert size of type
* Add Start/End subquery node skeleton
* Add Start/End subquery node creation to ExecutionNode
* Cleanup SubqueryEndNode
* Add test file
* Add isEqualTo to ExecutionNode
* Subquery nodes cleanup
* Update ExecutionNode tests
* Added API and tests to consume ShadowRows. Interface is there and compiles with templates, we might need to implement further underlying functions later on as we make progress on ShadowRows, it is only implemented in the minimal way (intentionally)
* Updates to testing code
* Added a test for nested ShadowRows and adapted OutputRow accordingly.
* More updates
* Add optimizer rule
* Fix optimizer rule
* Added additional memory include, seems to be required under GCC not udner CLANG
* it actually helps to save fies before commiting them...
* Fix optimizer rule (again)
* Fixed serialization/Deserialization of AqlItemBlock to contain the hidden subquery register now
* Added a c++ test for AqlItemBlock. It just covers the basics thus far and needs to be improved.
* Fixed toVPack of AqlInputRow for subqueries. Also added serialization / deserialization tests for AqlItemRow
* Added a c++ test for inputAqlItem row serialization => AqlItemBlock deserialization
* Add a public function to get plan from query
* Fix register planning
* Add test for splicing subquery nodes
* add static asserts for sizes of SubqueryStartNode and SubqueryEndNode
* Add comment about statically asserted size
* Fix isEqualTo virtual and override dance.
* Attempt to fix :windows: compile warning
* Fix isEqualTo, remove static_assert_size
* Remove a TODO; the plan owns the ExecutionNodes
* Only add stealPlan to Query when testing
* Remove another static_assert_size
* Fixed mac compile issues
* Initial commit, added class and test stubs
* Added Executor body stub, also added a test for no input. Passes now, as no input is read yet.
* Base implementation + Test of SubqueryStart Executor. First level shadowRows are now produced. Need to add tests for multilevel, and for non-fitting output blocks.
* Added more sophisticated test about shadow row relevance
* Added a test where ShadowRow does not fit into the open block. Also added disabled test on multi level shadowrows. Requires modifications on SingleRowFetcher.
* Added a serialization format to be backwards compatible to 3.5 whenever AQL item blocks need to be send over to remote nodes.
* Handle ShadowAqlItemRow in SingleRowFetcher
* Move some code from header to cpp
* Added more tests for serialization of shadow rows, and fixed a bug revealed by this
* Apply suggestions from code review
Thank you for review!

* Review comments. Thanks for spotting
* Fixed hidden merge conflicts
* Removed unused variable
* Added first test on ShadowRows in SingleRowFetcher. Found inconvenience in original code with it.
* Added a test for multi level shadow rows
* Added a test and fixed production for multiple consecutirve shadow rows.
* Added tests for pass through blocks and shadow rows
* Attempt to explain windows on how one can actually cast numbers into other number types...
* Adapted RowFetcherHelper to be able to work on ShadowRows
* Seperated assert, to see faster which part is violated
* Fixed minor error in RowFetcherHelper that causes LIMIT tests to error
* Temporarily disabled test suites (sorry there is only one 'test case' in this suites that does all or nothing tests ...) as it tests a feature we cannot support in this intermediate state, we need to default disable our new rule first.
* Improve check of ExecutionState
* Implemented shadow row handling in subquery start executor. Tests not happy yet
* IMplemented missing function to copy over SubqueryDepth between blocks
* Fixed test code of StartExecutor test. It asserted wrongly on releveance of subquery rows.
* Added instanciation of SubqueryStartExecutorTest. Code does not compile.
* Allow to create SubqueryStartExecutors.
* Update arangod/Aql/AqlItemBlockSerializationFormat.h
